Never miss a local story.

On Oct. 17, a jury found 31-year-old Earnest Daise guilty of murdering his ex-girlfriend, Jeanine Mullen, and her 4-year-old son Waltfredo Davis-Mullen and sentenced him to life in prison -- a case and trial that was a marathon of its own, the prosecutor said.

On Wednesday, that jury sentenced Daise to life in prison.

"You're physically and mentally exhausted at the end of a trial," Stone said. "In fact, we've always referred to them as an endurance race."

Both the Marine Corps Marathon and the trial required tremendous preparation and dedication, Stone said. After the trial ended last week, he was exhausted.

Four days later, the literal marathon ended with a medal in hand and congratulations from and for the Marines competing in the race.

"It was inspiring," Stone said. "You're running alongside people who have lost limbs in battle, and you see all the Marines lined up and down the street."

Sunday's event was Stone's first full marathon. He had been training for the race since February, when he ran in the Hilton Head Island Half Marathon. Stone squeezed in final training runs for the race just before the Daise trial began Oct. 14.

Stone also used the race to raise money for Beaufort County's Marine community and the three servicemembers who work in his office. As of Wednesday, he had raised nearly $1,000 for the Marine Corps Scholarship Foundation, which provides need-based scholarships to military children.
